Target Details

Target: PD-1 (PDCD1) (Programmed Cell Death 1 (PDCD1))

Alternative Name: PD-1

Background: Programmed Death-1 receptor (PD-1), also known as CD279, is type I transmembrane protein belonging to the CD28 family of immune regulatory receptors.PD1 is a inhibitory receptor on antigen activated T-cells that plays a critical role in induction and maintenance of immune tolerance to self. Delivers inhibitory signals upon binding to ligands CD274/PDCD1L1 and CD273/PDCD1LG2 (PubMed:21276005). Following T-cell receptor (TCR) engagement, PDCD1 associates with CD3-TCR in the immunological synapse and directly inhibits T-cell activation.

Molecular Weight: 41.6 kDa. Due to glycosylation, the protein migrates to 64-68 kDa based on Tris-Bis PAGE result.
